Optimization of glue dot quality
If you increase the plunger setting >0.6mm (>60N ), this also increases the spring pre-tension in
the jet valve. The consequence of this is that the glue dot is dispensed with more power. This can
lead to improvements when using adhesives which have a high viscosity.
If you increase the plunger setting, less adhesive flows into the dispenser nozzle between the indi-
vidual "shots". This means that, although the number of shots remains the same, a lower volume of
adhesive is applied to the component. Depending on the viscosity of the glue and the type of
component surface, this might cause the glue dot to have a wider diameter. The cause for this is
that the glue is dispensed with greater power and therefore at a higher speed. This change must be
taken into account when setting the characteristic line, in relation to the glue dot check by the Vis-
ion system.
Furthermore, a higher plunger setting will lead to flatter glue dots, if the number of shots remains
the same. Check whether the contact between the glue dot and the board is present and increase
the number of shots where necessary.
We recommend that the plunger setting only be increased as far as really needed. Changes to the
plunger setting are only advisable if you are using other glues than those recommended by us. Ob-
serve in particular the information about increased wear of the jet plunger and at the dispenser
nozzle.
If you reduce the plunger setting <0.6mm (<60N), the characteristics will change in the opposite
direction to that described above. To make sure that the shape of your glue dot is acceptable, you
should not set the jet plunger to <0.2mm (<20N).
The jet plunger setting range is between 0.2mm and 1.5mm (20N to 150N).

2.3 Glue Dot Inspection and Teaching with SIPLACE Vision
During the glue dot inspection, the glue dot is dispensed and then visually checked using a cam-
era. In order for a glue dot to be recognized and evaluated by SIPLACE Vision, a reference image
of the component is made just before the glue is applied to the component. This image is then
compared to the current image in which the glue has already been applied.
During a measurement job with glue dot inspection, the following is checked for each glue dot:
●
Is the glue dot present?
●
Is the size of the glue dot within the prescribed tolerance i.e. is the measured diameter of the
glue dot between the minimum and maximum circular area in the model?
●
is the glue dot within the prescribed target area? A rectangular target area can be defined in
the model. The inspection then checks whether the glue dot is completely within this target
area. If the glue dot touches the edge of the target area, an error will be reported.
Separate illumination can be set for the glue dot inspection as an option.
The following glue dot parameters can be changed in the CS Editor, with the station software:
●
Inspection (yes/no)
●
Tolerance for diameter of glue dot
●
Coordination of target area (size)

3 Initial Operation
NOTICE
Preconditions
Furthermore, the machine at which you want to use the Glue Feeder must already be fitted
with a connection to the safety circuit and a connection to the compressed air supply
WARNING
Protective clothing
Wear your personal protective clothing (protective goggles and gloves) for all work using or
on the Glue Feeder.
NOTICE
Calibrating the temperature regulation at all Glue Feeders
When taking a new Glue Feeder into operation in a production environment which already
uses other Glue Feeders, we recommend calibrating the temperature regulation of all Glue
Feeders. Calibrate with the "Glue Feeder calibration device" (item no. 03214618-xx), see
4.3.3
"Calibrating the temperature regulation" [}64].
The following steps must be completed in the prescribed order for setting up the Glue Feeder for
operation:
●
Insert the glue cartridge into the Glue Feeder
●
Place the Glue Feeder onto the setup location
●
Connect the Glue Feeder to the machine safety circuit
●
Connect the Glue Feeder to the machine compressed air supply
●
Predose the Glue Feeder i.e. distribute the glue in the glue unit (feed pipe, jet block and dis-
penser nozzle)
